Use FasTrak on the I-15 Express Lanes, South Bay Expressway, and a growing list of California toll roads and bridges! You can use your FasTrak transponder wherever you see the FasTrak symbol.

FasTrak Tolls

Tolls on the I-15 Express Lanes vary between 50 cents and $8, depending on distance traveled and traffic in the lanes. South Bay Expressway tolls vary depending on distance and whether or not a FasTrak account is being used. Review the toll calculator at SBXthe125.com for prices.

FasTrak Fees

There is a $3.50 minimum monthly toll (MMT), plus $1 for each transponder associated with an account. The MMT can be applied to your monthly toll usage. If you don't spend $4.50 per month in tolls, your account will be assessed the difference, up to a total of $4.50, for an account with one transponder. Your MMT will be automatically deducted the following month. For example, your May MMT would be deducted in June.

Only tolls paid electronically on the I-15 Express Lanes or South Bay Expressway with a valid FasTrak transponder count toward the MMT for SBX and I-15 accounts. Transactions on other FasTrak toll roads and bridges (outside San Diego) do not count toward the MMT.

Note: In order to avoid unnecessary fees, make sure your credit card and license plate information is updated in your account.
